Write a php program that checks the elements of a string array named $passwords. use regular expressions to test whether each element is a strong password. for this exercise, a strong password must have at least one number, one lowercase letter, one uppercase letter, no spaces, and at least one character that is not a letter or number. (hint: use the [^0-9a-za-z] character class.) th e string should also be between 8 and 16 characters long.

<?php

function pass_strong($candidate) {

   if (!preg_match_all('$\S*(?=\S{8,})(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])(?=\S [\W])\S*$', $candidate))

       return FALSE;

   return TRUE;

}

/*

   Explaining

   $\S*(?=\S{8,})(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])(?=\S*[\W])\S*$

   $ = string beginning

   \S* = characters set

   (?=\S{8,}) =  with length atleast 8

   (?=\S*[a-z]) = with at least 1 letter that is lowercase

   (?=\S*[A-Z]) = with at least 1 letter that is uppercase

   (?=\S*[\d]) = with at least 1 number

   (?=\S*[\W]) = with at least 1 special character

   $ = string end

*/

$Passwords = 'password01';

if(pass_strong($Passwords))

   echo "$Passwords is a strong password<br />";

else echo "$Passwords is NOT a strong password<br />";

?>

that without the operating systems you would have to control and synchronize computer hardware.

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.
